Component rls unavailable for download - README hints do not suffice #1758
Description
The README says to pin to a specific version found at https://rust-lang.github.io/rustup-components-history/ – however, that site only shows the last 7 days. It currently (at time of writing: 2022-01-10) does not even list "rls" anywhere, likely because no recent RLS builds are available for the nightly toolchain. Thus, I had to trick around like this
for n in $(seq 10 30); do if rustup toolchain add nightly-2021-11-${n} -c rls; then break; fi; done
in order to find that the latest available toolchain with RLS was 2021-11-09 at the time.
Other, more obvious solutions such as finding the latest successful CI build (linked from the button in the README: https://github.com/rust-lang/rls/actions?query=workflow%3ACI+branch%3Amaster) did not work for me, likely because their date does not necessarily relate directly to the (nightly) toolchain release date.
Having to pin a version isn't super bad, but then users should be given better hints how to solve it. Modern Rust projects often require nightly builds, so having RLS is essential for developer experience.
